Gigabyte 890FX-A UD7 Review
Test Setup and Overclocking
Our test setup consists of our standard AMD test rig. We'll also be comparing the UD7 to our two most recently tested AMD platforms, the MSI 870A Fuzion and the ASUS Crosshair 4 Extreme. So our graphs are all at stock, but we've included an overclocked result for the UD7, just to show the benefits you can have if you wish to go down the overclock route.

Overclocking on the UD7 was slightly different to most other AMD boards we've tested recently. It just took a little bit longer to work your way around the settings and discover what exactly the board needed and where, to get the maximum out of it.
But as you'll see, it's worth the extra effort.
There are three major elements that go into an AMD overclock, so our first task was to find the highest that each would reach, before consolodating them into our final overclock.
Here we have a very nice 3240.1MHz on the HT Link.
Regardless of the various tweaks and adjustments that have occured over the years, to a certain degree it's still all about the speed of the Bus. The UD7 gives us an exceptional 380MHz which really should give us a good overclock on our 1090T processor.
The Northbridge responds equally well with 3250MHz the best stable clock we obtained. If you're one of those people who loves good memory speeds, the UD7 has you covered there too.
So with plenty of overhead available to us from the three main elements of the overclocking process thanks to the quality of the major parts in the UD7, our best stable overclock, and that which we'll be using for our overclocked tests on the following pages, was 4.185 GHz. Not shabby at all and a couple of hundred MHz better than we saw from either the Crosshair or the Fuzion. It's not so easy to get there as those two boards, but definitely worth the extra time.
The main problem with getting the overclock is that the exceptional Bus Speed we saw above just couldn't be held at higher CPU speeds. Having a major Bus Speed is all well and good if it is easy to keep stable when the processor multiplier is increased again.
Still we got a great overclock and that's the important thing.
